6-2. WEIGHT AND BALANCE CRITERIA
Use the delivered weight as recorded in the Weight and Balance Record in−
serted in this section to perform all weight and balance computations. Deliv−
ered weight includes oil and unusable fuel.
6-3. EQUIPMENT REMOVAL OR INSTALLATION
Removal or addition of equipment must be entered on the repair and alteration
report form, FAA 337, in accordance with Federal Air Regulations which shall
then become part of the helicopter log book file.
Record the weight and balance effects of these changes in the Weight And Bal−
ance Record inserted in this section.
Use the balance and station diagrams shown as an aid for weight and balance
changes.
6-4. WEIGHT AND BALANCE DETERMINATION - PASSENGER
CONFIGURATION
To determine that the gross weight and longitudinal center of gravity (fore and
aft) for a given flight are within limits, proceed as follows.
Obtain aircraft delivered weight and moment from the Weight and Balance
Record inserted in this section.
Determine weights and moments of useful load items.
Add above items (Ref. Example I ).
Determine corresponding center of gravity for gross weight by dividing total
moment by gross weight. This computation must be done with zero fuel
gross weight and with mission fuel gross weight (Ref. Example I ).
NOTE
:
If loadings are not symmetrical about the aircraft centerline, determine lateral
CG’s as described in Paragraph 6-6.
Weight and balance must be computed for minimum front seat
weight prior to loading any passengers in rear seats with only pilot
in front. Ballast, if required, must be carried.
NOTE
:
Ballast may be carried in the utility stowage compartment or stowed and secured
by seat belt and shoulder harness in opposite front seat. Ballast may consist of
shot, sandbags, or similar material, adequately contained and secured.
